To determine which restaurant has more consistent delivery times, we need to calculate the range of the delivery times for both restaurants.

Restaurant 1 Delivery Times:

40, 37, 40, 41, 38, 46, 41, 37, 40

Finding the Range for Restaurant 1:

Minimum: 37
Maximum: 46
Range: Maximum - Minimum = 46 - 37 = 9 minutes

Restaurant 2 Delivery Times:

42, 38, 37, 39, 38, 40, 42, 41, 40

Finding the Range for Restaurant 2:

Minimum: 37
Maximum: 42
Range: Maximum - Minimum = 42 - 37 = 5 minutes

Comparing the Ranges:

Range for Restaurant 1: 9 minutes
Range for Restaurant 2: 5 minutes

Since the range of delivery times for Restaurant 2 (5 minutes) is lower than that of Restaurant 1 (9 minutes), this indicates that Restaurant 2 has more consistent delivery times.

Thus, the correct response is: Restaurant 2 is more consistent, because the range of its delivery times is lower than that of Restaurant 1.
