Answer:
21.66 km
Explanation:
Distance covered in first 10 min. = 40 x (10/60) km. = 20/3 km.
Distance covered in second 15 min. = 60 x (15/60) km. = 15 km.
Total distance = (20/3) + 15 = 65/3 = 21.66 km.

Answer:
11.66 km
Explanation:
FIRST 10 KMs
40 km per hour
speed of 1 min
40/60=0.66
TOTAL DISTANCE IN FIRST 10 MINs
0.66*10=6.66
2nd 10 KMs
30 km per hour
speed of 1 min
30/60=0.5
TOTAL DISTANCE IN 2nd.10 MINs
0.5*10=5
TOTAL DISTANCE COVERED BY THE CAR
first 10 min.s distance +2nd.10 min.s distance
= 6.66+5
= 11.66 ans.
