Calculation - km/hour?

520/30=17.33333 m/s

(17.3*3600)/1000=62.4km/h

520/30.5=17.05 m/s

(17.05*3600)/1000= 61.4 km/h

Hope that helps..

The conversion from metres per seconds to kilometres per hour is *3600 then /1000 incase you didnt pikc that up =)

1)
520 m/30 sec
= 1040 m/min
= 1.04 km/min

1.04 km/min
= 1.04 km/min x 60 min
= 62.4 km/h

= = = = = = = =

2)
520 m/30.5 sec
= (62400/61) m/min
= 62.4/61 km/min

62.4/61 km/min
= 62.4/61 km/min x 60
= 3744/61 km/h
= 61 23/61 km/h

62.4 Km/hour

have no time to explain!!!!!!!!!!!!!!!!!!!!

520m =520/1000km=.52km
30seconds=1/3600*30 hours

.52km/1/3600*30hr

62.4km/hr

.52km/1/3600*30.5hr
61.38km/hr

Greyhound 1
Speed = distance / time

520 x 3600
-------------- km/h
1000 x 30


62.4 km/h


Greyhound 2
Speed = distance / time

520 x 3600
-------------- km/h
1000 x 30.5

Speed = 61.4 km/h

SPEED=DISTANCE/TIME

CONVERT THE VALUES GIVEN IN REQUIERD FORMAT

fOR FIRST PROBLEM

distance=520/1000 kms
time = 30 /3600 hrs

KM/HR=(520/1000)/(30/3600)
= (520 X 3600)/(30 X 1000)
= (52 X 36)/(30 X 1)
= 62.4 KM / HR

SECOND PROBLEM CAN BE SOLVED SIMILARLY

520m/30s x 60s/1min x 60min/1h x 1km/1000m = 62.4 km/ hour

.52(120) = 62.4 km/hr

.52/30.5/3600=61.38 km/hr
