Answer 1

Answer:

The formula which relates distance, speed, and time is:

d = rt, where d is the distance traveled, r is the rate of travel or speed, and t is the time traveled.

Since we're given that r = 60 km./hr. and time t = 2 hrs. 20 min., then we can find time d traveled by the bus by substituting the given information into the distance-speed-time formula as follows:

d = rt

d = (60 km./hr.)(2 hrs. 20 min.)

= (60 km./hr.)(2⅓ hrs.)

NOTE: 20 minute = ⅓ of an hour.

= (60)(7/3) km.

NOTE: 2⅓ = 7/3

= (60/3)(7) km.

= (20)(7) km.

d = 140 km. is the distance a bus traveling at 60 km./hr. can travel in 2 hrs. and 20 min.

Answer 2

Answer:

30 km,21 hours

Step-by-step explanation:

1 min car travels=250 m

1hour=60 minutes

so the car will cover distance in 2 hrs

=250×120 =30000 m

the car covers 30km in 2 hrs

so the car will cover 15 km in 1 hr

time taken by the car=315/15=21 hrs
