Answer:
1.7 hours
Explanation:
Time taken in the journey = 3 hours
Distance of the entire journey = 197 miles
Distance travelled on train = x
Distance travelled on bus = 197-x
Average speed of train = 70 mph
Average speed of bus = 60 mph
Time = Distance / Speed

Distance travelled by train = 119 miles
Time taken on train = 119 / 70 = 1.7 hours
Manuel spent 1.7 hours on the train
If the runner ends where she started, then her total displacement is
, which means her average velocity will be

The total distance she traversed, however, was
, which gives her an average speed of

Answer:
d)energy
Explanation:
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
Condensation does not effect the temperature of the area, condensation is the product the temperature difference between an object and the area it is in
