Answer 1

Hello There !

Explanation :-

• Intial reading of the Odometer of the Car = 57321.0 .

• Final Reading of the Odometer of the car = 57336.0 .

Distance covered by the Car ,

=> [ Final reading of the Odometer of the car ] - [ Final Reading of the Odometer of the car ]

=> 57336.0 - 57321.0 = 15km .

Time taken by the car = 20mins .

$speed \: = \frac{distance \: covered}{time \: taken} = \frac{15}{20} = 0.75 \: km \: per \: min.$

Again ,

$60 \: mins \: = \: 1 \: hr$

$20 \: mins \: = \frac{1}{60} \times 20 = \frac{1}{3} hr$

$speed \: = \frac{distance \: covered}{time \: taken} = \frac{15}{1} \div 3 = 45 \: km \: per \: hr$

Hope this helps you ..!

Have a nice day ahead ..!
