Answer 1

Answer:

Step-by-step explanation:

Case I

T = 12hrs

S = 60km/h

D = S*T = 60*12 = 720 km

Case II

Let the speed be increased by 'x' km/h.

D = 720 km

T = 10 hrs

S = (60 + x) km/h

D / T = (60+x)

720/10 = 60 + x

72 = 60 + x

x = 72 - 60

x = 12 km/h

Hence the speed of the car should be increased by 12 km/h.
