The relationship between the number of workers, the time taken, and the amount of work done is given by the formula: Work=Rate×TimeWork=Rate×Time Let's assume that the amount of work required to build the wall is WW. So, the rate of work for 15 workers is W4848W (work done per hour). Now, if you want to find out how many workers are required to do the same amount of work in 30 hours, you can set up the equation: W30=Rate×Numberofworkers30W=Rate×Numberofworkers Given that the rate is W4848W for 15 workers: W30=W48×Numberofworkers30W=48W×Numberofworkers Now, solve for the number of workers: Numberofworkers=W30W48Numberofworkers=48W30W Numberofworkers=4830Numberofworkers=3048 Numberofworkers=85Numberofworkers=58 So, 8558 workers are required to do the same work in 30 hours. Since the number of workers cannot be in fractions, you might need to round up or down based on practical considerations. In this case, rounding up makes sense, so you would need 2 workers to complete the same work in 30 hours. read less
