Write an expression for the number of kilometers a dolphin travels in d hours swimming at 8 km/h.?

distance = r *t

where
r = rate in km/hour
d = time in hours

distance = 8*d

For 3 hours, you get 24 km

= 3 hrs * 8 kph
= 24 km

Dolphin Travels

i might evaluate it, yet do you recognize how lots a undergo eats? particular, i could feed the dolphin to it, yet what approximately whilst the dolphin's all long previous? rather quickly, i will start off looking like a rather tasty morsel and that rattling undergo isn't getting any smaller. toddlers might eat lots, yet no longer as much as a undergo and that i'm rather particular they gained't eat me. Edit: look, if it makes you experience any further suited, i could talk approximately feeding the undergo to the dolphin, yet i think of I took the easy-experience path, which dictates that the dolphin be the single to get eaten. after all, who ever heard of a dolphin ingesting a undergo? Please do no longer difficulty to point out that no-one has ever heard of a undergo ingesting a dolphin the two, as a results of fact my palms are over my ears and that i'm buzzing a track loudly.

d = st (d = distance , s = speed , t = time)

8 km/h x 3 hours
= 24 km

(the number of kilometers a dolphin travels)=(d hours) (swimming at 8 km/h)

N=D(8)

then plug in 3 for D and solve

no. of km.=time * speed=d*8=8d
the number of kilometers the dolphin travels in 3 hours=3*8=24km.
