Question

If a snail travels 48 inches per hour, which metric measures are faster than 67 inches per hour?

a) 1.8 m/min
b) 1.5 m/min
c) 1.2 m/min
d) 1.0 m/min

Answer 1

Option a) 1.8 m/min, option b) 1.5 m/min, and option c) 1.2 m/min are faster than 67 inches per hour.

Step-by-step explanation:

The snail travels at a speed of 48 inches per hour. To determine which metric measures are faster than 67 inches per hour, we need to convert the speeds to meters per minute.

1 inch is equal to 2.54 centimeters. Therefore, 48 inches per hour is equal to (48 * 2.54) cm/hour.

To convert cm/hour to meters/minute, we divide by 100 to convert from centimeters to meters, and then divide by 60 to convert from hours to minutes.

So, (48 * 2.54) cm/hour is equal to ((48 * 2.54) / 100) m/minute, which simplifies to (1.2192 / 100) m/minute, which is approximately 0.012192 m/minute.

Among the given options, option a) 1.8 m/min, option b) 1.5 m/min, and option c) 1.2 m/min are all faster than 0.012192 m/minute. Therefore, the metric measures that are faster than 67 inches per hour are a) 1.8 m/min, b) 1.5 m/min, and c) 1.2 m/min.
