Question

the odometer of a car reads 2040 km and 2094 km respectively in a time interval of 30 minutes. find the average speed of the car in km/h and m/s.

Answer 1

Answer:-

• Reading at first =2040km
• Reading at last=2094m
• Time=30min=0.5km

We know that

$\boxed{\sf Average\:Speed=\dfrac{Total\;Distance}{Total \;time}}$

$\\ \sf\longmapsto Average\:Speed=\dfrac{2094-2040}{0.5}$

$\\ \sf\longmapsto Average\:speed=\dfrac{54}{0.5}$

$\\ \sf\longmapsto Average\:speed=108km/h$

$\\ \sf\longmapsto Average\:speed=30m/s$
