Question

The average curvature of a car over a particular stretch of elephant is 60 km / h. The average speed on a given day was 5 times slower than normal and as a result it took more than 15 minutes. How long is the road in kilometers?​

Answer 1

Step-by-step explanation:

given,

speed= 60

reduced speed is 5times slower

so = 60-60/5= 60-12= 48

let the distance be d

a/q

d/48-d/60= 15/60

5d/240-4d/240= 1/4

d/240=1/4

d/60=1

d= 60

hence distance is 60 km

...666....
