Answer :
Answer:
t=1.6h
Step-by-step explanation:
This question is asking to find change in time with knowns of average velocity and displacement.
This is the formula used for problems related to Velocity.
v= x / t
v= average velocity
x= displacement
t= change in time
a. identify knowns
v = 61mi/h
x = 97.6mi
b. plug in values
61mi/h = 97.6mi / t
c. Multiply all terms by the same value to eliminate fraction denominators.
t ⋅ 61 mi/h = t ⋅ 97.6 / t
d. Cancel multiplied terms that are in the denominator.
61 mi/h ⋅ t = 97.6mi
e. Re-order terms so constants are on the left.
61 mi/h ⋅ t = 97.6 mi
f. Divide both sides by the same factor.
61 mi/h ⋅ t / 61 mi/h = 97.6 mi / 61 mi/h
g. simplify
t = 1.6 h
Check unit of measurement
Time is measured in hours.
therefore, t = 1.6 h
