Question

1. A truck departed from newton at 11:53a.M. And arrived in far city, 240 miles away, at 4:41 p.M. On the same day. What was the approximate average speed of the truck on this trip?

Answer 1

total time = 312 min

and total distance = 240 miles

speed = distance /time

= 240/312

= 0.7692 miles/ min

speed = 46.15 miles/ hour

that is required ans

Answer 2

The approximate average speed of the truck on this trip is 50 mph

Solution:

Given that,

Distance = 240 miles

A truck departed from newton at 11:53 a.m and arrived in far city at 4:41 p.m

Total time = 11 : 53 am to 4 : 41 pm

Total time = 4 hours 48 minutes

We know that,

1 hour = 60 minutes

Therefore,

4 hours 48 minutes = 4 hours + 0.8 hours = 4.8 hours

The average speed is given as:

$speed = \frac{distance}{time}\\\\speed = \frac{240}{4.8} = 50\ mph$

Thus approximate average speed of the truck on this trip is 50 mph
