• A. 86 km per hour
• B. 76 km per hour
• C. 66 km per hour
• D. 56 km per hour

Answer 1

The correct option is B 76 km per hour

Total distance to be covered = 3724 km
Total time spent = 49 hours

You know,
$Speed=\frac{Totaldistance}{Totaltime}$

So, in the case of the artist:
$Speed=\frac{3724km}{49hours}$

∴ To find the speed, to divide 3724 km by 49 hours.

Calculating $3724÷49$ by standard algorithm,

So, the final quotient of $3724÷49$ is $70+6=76$

∴ The speed at which the artist covered $3724km$ is $76kmperhour$.
