When you normally drive the freeway between Sacramento and San Francisco at an average speed of 105 km/hr (65 mi/h ), the trip takes 1.00 hr and 20 min . On a Friday afternoon, however, heavy traffic slows you down to an average of 90 km/hr (56 mi/h ) for the same distance.
How much longer does the trip take on Friday than on the other days? (Express your answer in minutes to the nearest integer.)

Sagot :

Answer:

13 minutes

Explanation:

Distance traveled

105 km/hr(1⅓ hr) = 140 km

140 km / 90 km/hr = 1⁵/₉ hr

1⁵/₉ - 1⅓ = ²/₉ hr

²/₉(60) = 13⅓ minutes
