151.58

Step-by-step explanation:

Answer 2

151.58 miles

Step-by-step explanation:

given,

total trip time = 4 hr

speed when drove to a friends house = 40 mph

speed when drove back = 45 mph

`(x)/(40) + (x)/(45) = 4`

40 x + 45 x = 4 × (45 × 40)

95 x = 7200

x = 75.79 miles

Total distance travel by michael is 2 x = 2 × 75.79 = 151.58 miles
