Question

How many minutes does it take to drive 20 miles to Dallas if you are driving 55 miles /
hour?

Answer 1

• Distance=20miles
• Speed=55mph

$\\ \sf\longmapsto Time=\dfrac{Distance}{Speed}$

$\\ \sf\longmapsto Time=\dfrac{20}{55}$

$\\ \sf\longmapsto Time=0.36h$

$\\ \sf\longmapsto Time=22min$

Answer 2

Answer:

$\dashrightarrow \: { \tt{time = \frac{distance}{time} }} \\ \\ \dashrightarrow \: { \tt{time = \frac{20}{55} \: hours }} \\ \\ \dashrightarrow \: { \tt{time = (\frac{20}{55} \times 60) \: mins }} \\ \\ \dashrightarrow \: { \boxed{ \tt{time = 21.8 \: minutes}}}$
