Question

A car travels 1000 km in a time of 10 hours. What is the car’s speed?

Answer 1

100km/hr

Explanation:

s=d/t

speed=distance/time

s=1000/10

s=100

Answer 2

`\boxed{v=100\ (km)/(h)}`

Explanation:

`v=(d)/(t)\\\\v-speed\ (velocity)\\d-distance\\t-times\\\\\text{We have}\ d=1,000\ km,\ t=10\ h.\\\\\text{Substitute:}\\\\v=(1,000\ km)/(10\ h)=100\ (km)/(h)`
