Question

It take a bus 1 hour and 30 minutes to travel 48 miles

Calculate the average speed of the bus in mph
if your answer is a decimal, give it to 1 d.p

Answer 1

Explanation:

48 miles in 1 hour 30 minutes (1.5 hours = 3/2 hours).

speed = distance/time

as mph is requested, the time is 1 hour.

in our case the direct speed ratio is

48/1.5

to bring that to the regular miles per 1 hour we need to transform it. here I would use fractions and simplify :

48/1.5 = 48/ 3/2 = (2×48)/(3×1) = 96/3 =

= 32/1 = 32 mph

the speed of the bus was 32 mph.
