Question

Cesar drove his car to Mexico to visit relatives. The speed limit sign on the freeway said 110 kilometers per hour, but the speedometer on Cesar’s car is calibrated in miles per hour. How fast should Cesar drive his car to avoid a speeding ticket if 1 kilometer is about 0.62 miles?

Answer 1

Cesar should drive at 68.2 miles per hour or less, which is the equivalent of 110 kilometers per hour, to avoid a speeding ticket.

Step-by-step explanation:

To determine how fast Cesar should drive in miles per hour to stay within the 110 kilometers per hour speed limit in Mexico, we need to convert kilometers per hour to miles per hour. The conversion factor given is that 1 kilometer is about 0.62 miles. To get the speed in miles per hour, we can multiply the speed limit in kilometers per hour by this conversion factor.

Convert 110 km/h to mi/h:

• Speed limit in km/h = 110 km/h
• Conversion factor = 1 km ≈ 0.62 miles
• Speed limit in mi/h = 110 km/h * 0.62 mi/km ≈ 68.2 mi/h

Therefore, Cesar should drive at 68.2 miles per hour or less to avoid a speeding ticket.
