Question

the odometer of a car reas 57321 point zero kilometre when the clock shows the time 8:30 a.m. what is the distance moved by the car, if at 8:50 a.m., the odometer reading has changed to 5733 6.0 kilometre. calculate the speed of the car in kilometres/minute during the time. express the speed in kilometre per hour also​

Answer 1

Step-by-step explanation:

so here we see that the odometer will give us the distance travelled by the car

so the distance travelled will be:

57336-57321=15km

now the time taken will be:

8:50-8:30=20min

so the speed will be:

15/20=0.75km/min

in km/hr:

15km/(20/60)hr=15/(1/3)=45km/hr

$\frac{15}{20\div 60?} = \frac{15}{1 \div 3} = 15 \times 3 = 45$

hope this helps you and please mark it as the brainliest
