Answer:
1,2,4,5 and 7
Step-by-step explanation:
I just took the quiz on edge
The time taken by Mark will be 0.23 hours and the time taken by Jesse will be 0.40 hours.
What is speed?
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Jesse and Mark are jogging along the route shown at a rate of 12 miles per hour.
They start by jogging south along Capitol Street for 1 mile, then turn east on H Street and jog for 1.75 miles.
At that point, Jesse is tired and decides to walk home along Florida Avenue at a rate of 5 miles per hour.
Then the time taken by Jesse will be
T = [√(1.75² + 1²)] / 5
T = 0.40 hours
Mark plans to jog back the way they came.
Then the time taken by Mark will be
T = (1.75 + 1) / 12
T = 2.75 / 12
T = 0.23 hours
Then the correct options are A, B, D, and E.
