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=(Distance)/(Speed)`

`\\ \sf\longmapsto Time=(20)/(55)`

`\\ \sf\longmapsto Time=0.36h`

`\\ \sf\longmapsto Time=22min`

Answer 2

`\dashrightarrow \: { \tt{time = (distance)/(time) }} \\ \\ \dashrightarrow \: { \tt{time = (20)/(55) \: hours }} \\ \\ \dashrightarrow \: { \tt{time = ((20)/(55) * 60) \: mins }} \\ \\ \dashrightarrow \: { \boxed{ \tt{time = 21.8 \: minutes}}}`
