Answer:
Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.
Explanation:
Since Alfred departs from NAMPO Park at 18:45 and travels to Sasolburg at an average speed of 88 km / h, and he calls his wife to inform her that he will arrive in Sasolburg at 8 pm, to determine if his estimate is correct the following calculations must be performed:
The shortest route from Nampo Park to Sasolburg in South Africa is 139 km via Route 59.
8 PM = 20:00
20:00 - 18:45 = 1:15
139/88 = 1.57
60 x 0.57 = 34.74
Thus, Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.
