Question

A car travels first 100 km in 5/2 hours and next 30 km in 1/2 hour. What is its average speed?​

Answer 1

Step-by-step explanation:

We know Speed = Distance / time

Distance given = 100 kilometer

Time = 5/2 hours = 2.5 hours

First Speed of car = 100km/2.5 hours

First speed of car = 40 kilometer / hour

For second speed:

Distance = 30 kilometer

Time = 1/2 hour = 0.5 hour

Speed = 30 km/ 0.5 hrs.

= 60 kilometer/hour

Average speed of car = 40 kiloneter/hr + 60 kilometer/ hour

= 100 kilometer/hr / 2

Average speed of car = 50 kilometer/hour

Answer Average speed of the car = 50 kilometer/hour
