Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom drove 65 mph and her dad drove 60 mph if they drove a total of 895 miles how many hours did each person drive for

Mom drove for 11 hours.

Dad drove for 3 hours.

Step-by-step explanation:

Let 'x' be the number of hours drove by mom.

Let 'y' be the number of hours drove by dad.

x + y = 14     (1)

65x + 60y = 895  (2)

Multiply eq(1) by 60 and subtract eq(2) from (1),

60x + 60y = 840

-(65x + 60y = 895)

  -5x   = -55    

x = 55/5

x = 11

∴ Mom drove for 11 hours.

Substitute x=11 in eq(1)

11+y = 14

y = 3

∴ Dad drove for 3 hours.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
