Averaging 75 miles per hr how long would it take to drive 732 miles?
回答 (10)
732 miles × (1 hour) / (75 miles) = 732/75 hours = 9 hr 45 min 36 sec
Time taken
= Distance / Speed
= (732 miles) / (75 miles/hr)
= 9.76 hr
Averaging 75 miles per hr how long would it take to drive 732 miles?
=732 miles (hr /75 miles)
= 732/75
= 9.76 h <==Answer
d = rt. t = d/r, d = 732 mi, r = 75 mi/hr = (3/4)100/(hr/mi) and d/r =
(0.01)(4/3)(732 mi)(hr/mi) = (.04)(244)hr = (0.01)(976)hr = 9.76hr. Those
who care can work out min and sec for themselves.
75 miles in 1hr
732 miles in x hr
75/732 =1/x
Cross multiplication:
(732*1)/75 = x
x = 9.76 hours
0.76 * 60 = 45.6 min
0.6 * 60 = 36 sec
Answer: 9 hours, 45 minutes, 36 seconds
miles divided by (miles per hour) gives you hours
t = 732 / 75 = 9.76 h = 9 h 46 mins
d=vt so t=d/v
t=732/75=244/25h
t~9:45:36 (9h,45min,36s)
