Explanation / Answer

11.

speed = 100 km/h

time of travel = 2.75 h

distance travelled = ?

Distance travelled is given as

Distance = speed x time

Distance = 100 x 2.75

Distance = 275 km

12.

speed = 105 km/h

time of travel = 3.85 h

distance travelled = ?

Distance travelled is given as

Distance = speed x time

Distance = 105 x 3.85

Distance = 404.25 km

13.

speed = 60 km/h

time of travel = ?

distance travelled = 265 km

Distance travelled is given as

Distance = speed x time

265 = 60 x time

time = 4.42 km/h

14.

speed = 55 km/h

time of travel = 3.65 h

distance travelled = ?

Distance travelled is given as

Distance = speed x time

Distance = 55 x 3.65

Distance = 200.75 km
