Sagot :

We need first to change the speed of miles per hour to meter per min, then compare both speeds

Since 1 mile = 1.61 km

Since 1 km = 1000 m, then

1 mile = 1 x 1.61 x 1000

1 mile = 1610 meters

Since 1 hour = 60 min, then

50 miles per hour = 50 miles / 1 hour

Multiply 50 by 1610

Multiply 1 h by 60

[tex]\frac{50miles}{hour}=\frac{50\times1610}{1\times60}[/tex]

Simplify it

[tex]\frac{50miles}{hour}=\frac{80500}{60}=1341\frac{2}{3}meters\text{ per min}[/tex]

Since the other speed is 1250 meters per min

Since 1341 2/3 > 1250

Then you have to drive at 50 miles per hour
