Answer:
The car must drive at 108 km/h to cover the same journey.
Step-by-step explanation:
Given that:
Time taken by bus journey = 45 minutes =
Speed of bus = 60 km/h
Distance of the journey = Speed * Time
Distance of the journey = 60 * 0.75 = 45 km
The car needs to cover 45 km in 25 minutes.
25 minutes =
Distance = Speed * Time
45 =
Speed =
Speed = 108 km/h
Hence,
The car must drive at 108 km/h to cover the same journey.
Question 5.
The function given shows represents height after a certain time. The distance measures is initial distance till the distance covered when the time is calculated. The question has given us an initial distance of 100 feet and they want us to calculate the time when the egg hits the ground, or, in other words, 0 feet. So, next, we substitute this information in the equation.
